    Assessing Australia\u27s National Integrity Framework: A New Way Forward

    Historically, Australia has not been regarded as a particularly corrupt country. In 2012, Transparency International ranked Australia as the 7th least corrupt country in its Corruption Perceptions Index. This ranking has deteriorated six places in four years; in 2016, Australia landed in 13th place on the same index. This sharp decline, in conjunction with continued revelations of corrupt conduct in the public, private and union sectors, has resulted in unprecedented national attention on corruption issues. As a result, the Australian federal government is currently considering a suite of reforms related to anti-corruption enforcement, including the introduction of deferred prosecution agreements, increased penalties for white collar crimes, the introduction of a new corporate foreign bribery offence, and the strengthening of whistle-blower protections. Included in this suite of proposals, on 8 February 2017, the Australian Senate referred an inquiry regarding the establishment of a national integrity commission to a Select Committee, which was charged with the following goal: to examine whether a National Integrity Commission (“NIC”) should be established at the federal level to address institutional, organisational, political, electoral, and individual corruption and misconduct in the federal public sector. The Committee is required to report back on its findings to the Senate on or before 22 September 2017

    Tropical imaginaries and climate crisis: embracing relational climate discourses

    Get PDF
    In this Introduction, we set the Special Issue on 'Tropical Imaginaries and Climate Crisis' within the context of a call for relational climate discourses as they arise from particular locations in the tropics. Although climate change is global, it is not experienced everywhere the same and has pronounced effects in the tropics. This is also the region that experienced the ravages – to humans and environments – of colonialism. It is the region of the planet’s greatest biodiversity; and will experience the largest extinction losses. We advocate that climate science requires climate imagination – and specifically a tropical imagination – to bring science systems into relation with the human, cultural, social and natural. In short, this Special Issue contributes to calls to humanise climate change. Yet this is not to place the human at the centre of climate stories, rather we embrace more-than-human worlds and the expansion of relational ways of knowing and being. This paper outlines notions of tropicality and rhizomatics that are pertinent to relational discourses, and introduces the twelve papers – articles, essays and speculative fiction pieces – that give voice to tropical imaginaries and climate change in the tropics

    Polyradical Character of Triangular Non-Kekulé Structures, Zethrenes, p -Quinodimethane-Linked Bisphenalenyl, and the Clar Goblet in Comparison: An Extended Multireference Study

    In this work, two different classes of polyaromatic hydrocarbon (PAH) systems have been investigated in order to characterize the amount of polyradical character and to localize the specific regions of chemical reactivity: (a) the non-Kekulé triangular structures phenalenyl, triangulene and a π-extended triangulene system with high-spin ground state and (b) PAHs based on zethrenes, p-quinodimethane-linked bisphenalenyl, and the Clar goblet containing varying polyradical character in their singlet ground state. The first class of structures already have open-shell character because of their high-spin ground state, which follows from the bonding pattern, whereas for the second class the open-shell character is generated either because of the competition between the closed-shell quinoid Kekulé and the open-shell singlet biradical resonance structures or the topology of the π-electron arrangement of the non-Kekulé form. High-level ab initio calculations based on multireference theory have been carried out to compute singlet–triplet splitting for the above-listed compounds and to provide insight into their chemical reactivity based on the polyradical character by means of unpaired densities. Unrestricted density functional theory and Hartree–Fock calculations have been performed for comparison also in order to obtain better insight into their applicability to these types of complicated radical systems

    Dielectric and Electrical Properties of LaGaO3 Ceramics

    LaGaO3 based perovskite oxides doped with Sr and Mg exhibit high ionic conductivity over a wide range of oxygen partial pressure and found to be very stable in reducing, oxidizing, and CO2 atmospheres. In this study, the polycrystalline sample of LaGaO3 was prepared by a high-temperature solid-state reaction technique. Preliminary X-ray diffraction (XRD) studies of powder sample of LaGaO3 showed the formation of single-phase compound at room temperature. The surface morphology of the pellet sample of LaGaO3 was recorded at room temperature using a scanning electron microscope (SEM). Detailed studies of dielectric properties (εr, tan δ) and impedance parameters of the material provide an insight into the electrical properties and understanding of types of relaxation process occurred in the material. Temperature variation of dc conductivity shows that this compound exhibits negative temperature coefficient of resistance (NTCR) and frequency dependence of ac conductivity suggests that the material obeys Jonschera's universal power law
